Abstract

Abstract Application of Intelligent Well Technology (IWT) is focuses upon monitoring and optimizing productions from oil wells (producer and injector) containing single tubing string completed in multiple pay zones. Wells producing under a water injection scheme are inevitably susceptible to water breakthrough. Once breakthrough occurs, the operator of the well is faced with a choice between continuing recovery at a reduced rate, or sacrificing recoverable oil. If the well is producing from multiple pay zones then the situation is more complicated, as breakthrough may occur at different times in different layers. IWT allows the operator to regulate production from each zone using Interval Control Valve (ICV). This paper presents a numerical modeling study that was performed to demonstrate that the IWT could be successful in optimizing reservoir management through controlled producer and injector in multi layers pay zones. The impact of IWT in term of economic viability was also investigated. The project considered a portion of Field-X reservoir that consists of two layers separated by fault. The two layers are connected at the left flank of the fault. A conceptual deviated producer and injector were implemented to simulate the functions of IWT. Numerical reservoir simulation was used to estimate the oil production profiles for base case with conventional completion and cases with intelligent completions. From the numerical and economic modeling, it can be concluded that the application of intelligent well technology has increased cumulative production of oil and most importantly, eliminate the need for future well intervention. Keywords: Interval Control Valve, numerical modeling
